Cholamu Lake : World's 14th highest and India's highest lake, the Cholamu Lake in North Sikkim is situated at an altitude of 18000 feet from the sea level.
Gurudongmar Lake is the second highest lake in India located at a height of 17100 ft above sea level, first being Cholamu Lake in Sikkim. Legend has it that, Guru Padmasambhava (also known as Guru Dongmar) once visited the place. Then people of that area asked for his help, saying that they cannot get water from the lake as the Lake remains frozen throughout the year. Then he touched a part of the lake and sanctified the lake, and then onwards even in extreme winter, a portion of the lake does not freeze.The view of the Lake is out of the world spectacle. Surrounded by snow capped mountains, beauty of the Lake is worth comparing with paradise. We stayed there for around 30 min. We also visited the Sarva Dharma Sthall next to the Lake. (Tips: Since the place is located at a very high altitude, certain precautions are always helpful. Our driver advised us to remain seated inside the car for 2-3 minutes after reaching the Lake, to adjust with the high altitude conditions. Even after getting down, he advised us to walk slowly as the oxygen level is less. We carried popcorn, ginger and dry fruits which can help in case of altitude sickness). Some of the visitors also went down to the lake to walk on the frozen Lake, which was something we didn’t try.On our way back we were again stopped by Indian Army, this time they offered us Mango juice, biscuits, chocolate etc. And who does not like free treats. We reached Lachung around noon. After having lunch and some rest we started for our next destination, Lachen.
At 17,480 ft, Tso Lhamo is a fresh water lake situated at close proximity to the Tibetan border. Tso Lhamo is another one of the afore mentioned 109 "Tso Chen" of Sikkim. This fresh water lake is the source of river Teesta and because it is so close to the border, you require an army-approved permit to enter.
